CHA3514-99F Datasheet - United Monolithic Semiconductors

CHA3514-99F 4-bit Digital Variable Amplifier

The CHA3514-99F is composed by a two stage travelling wave amplifier followed by a four steps digital attenuator. It is designed for defense applications. The backside of the chip is both RF and DC grounded. This helps to simplify the assembly process. The circuit is manufactured with a pHEMT proces.
